Refrigeration Training System

This integrated training system introduces students to the principles and components of a refrigeration system using industrial and commercial devices.

It clearly demonstrates the operation of the most common refrigeration sys- tem configurations, including dual evaporator systems. Lockable fault- insertion switches allow students to practice troubleshooting skills, which may be conducted at either the sche- matic control panel or at the suspect devices and components.

Fully integrated courseware guides students through alternative modes of system set-up and control. The train- ing system includes all the equipment required to perform the exercises con- tained in the courseware.
